White Horse Laboratories Week 17 Counterfeit Detection Report
70% Accept 73% Pass
Week 17 once again saw gains in both physical inspection and electrical testing results. Condition quality improved to 70% acceptance in Week 17 from 59% acceptance in Week 16 and functional performance leapt from 52% in Week 16 to 73% in Week 17. It is not overly surprising, then, that a higher percentage of acceptable product resulted in the highest volume week to-date, as measured by value.
While continuing to follow the supply chain effects of the now rebuilding process in Japan, that a significant volume of product from Japanese OCM are being sourced, the general quality level of these products has been quite good, with no rejected product in Week 17. Will continue to monitor and report on that as the impact of the natural disaster will likely have a significant impact on the industry throughout the course of 2011.
